Because there just isn't enough Mycroft and John friendship interaction out there...

Explosive

It wasn't the first time John had been accosted by the driver of an unmarked black sedan, though it was still irritating. After Moriarty's little trick at least Mycroft sent drivers he recognized, though they still refused to tell him anything.

It was only a matter of minutes before they arrived at a minorly charred-looking structure, which John glanced at resignedly before approaching a suit-clad, umbrella wielding figure watching from the sidelines. John asked pointedly, "My phone?"

"My apologies."

"Right. Where's Sherlock?"

Mycroft pointed his umbrella in the direction of a fuming shock-blanket covered figure standing next to a nearby ambulance. Despite himself, John smirked. Less than twenty-four hours in the area and the local medical crews already knew how to get on Sherlock's nerves. "Your idea?" he asked curiously.

"A mere coincidence, in truth. Though I must say it seems rather appropriate for the situation."

John nodded, already having put two and two together. "Experimenting with power sources," he finished resignedly. Trust Sherlock to take a vacation and turn it into a minor crisis in less than a day. The locals must love them.

"Do try to keep him out of trouble, will you?" the elder Holmes commented, and John glanced at him to see Mycroft's ever-faithful PA standing nearby, apparently waiting.

John's smile quirked across his face. "Given the current situation I wouldn't hold out too much hope."

"True." Mycroft nodded to him in farewell and was gone.

John's reluctant smile faded slightly as he took a deep breath. Now to diffuse this potentially – John glanced again at the building and nearly snorted – already explosive situation...
